INVENTOR BY fi lr 30W ATTORNEY I F. HIELSCHER, the United States, residing at King and State of have invented a certain new and useful Improvement in Clock-Controlled lectric Signal Systems, of which the following is a specification.

.L y invention relates to improvements in clock-controlled electric signal systems that are used in hotels, rooming houses and like places which signal systems shall embody mechanical devices for automatically controlling t e operation of the call-bells or other signals, and the f my invento provide a simple and efficient sig nal system that may be easily installed in 'e place that is wired for telephones or call-bells without ma ing extensive changes in the already installed Wiring.

A further object of my invention is to provide a signal system wherein an ordinary twelve hour clock may be utilized to drive the mechanical device that automatically controls the operation of the bells or signals.

A still further object of my invention is invention consists in the novel constructlon, adaptation and combination of parts as will be more clearly hereinafter described.

I accomplish these objects by devices illustrated in the accompanying drawings, wherein- Figure 1 is a my invention, plan views of certain c0ntrolling devices being shown in association with such diagram;

Fig. 2 is a plan view of a mechanically actuated circuit closing device embodied'in my invention; and

ig. 3 is a view tially on two rooms 4 y seen that the same may be extended to include any desired number of rooms by a simple duplication of parts.

Referring to the drawings throughout which like reference numerals indicate like parts. the

six 0(lOClill'l the evening, and the lower ha" of each of the dials 7 and 8 is marked to indica te the night lie innmg'at SIY oclock b he dials 7 and 8 a in a convenient manner to indicatethe rooms with which they are connected, as for-Vin stancfnthe dial 7 is indicate that it isconnected In the peripheral. and 8 whereon occur, there are contacts or terminals, w ich may e made at each iour mark and atas many points as desired between the adjacent hour marks.

ivotally secured to: the centers of the dials 7 and 8 s 10 portions of the dials Q oftime and the contact twenty four spaces correspondingtwenty four hours-of a complete day. rranged around the periphery of the bells '5 and 5.

for the purpose desired, are electrical contact members or terminals 16 that are each connected by suitable electrical circuitwires with correspond ing terminals on each of the dials 7 and 8 as more clearly hereinafter describe Secured on a post 17 in dial 15 is a contact arm 18 that is adapted to be movedvaround the face of the dial 15 to successively make contact vwith'the VitflOllS terminals 16. a

20 is van electrical circuit-wire that connects the post 17 with one terminal of a bat tery 21, the other" terminal 1 of the battery 21 being connected by a circuit wire 22 with the As previously stated, each of the terminals 16 on the dials 15is connected withcorresponding terminal'9 on the dials 7 and 8 but of illustrating my invention and avoiding (confusion only four of the circuit wires connecting these respective terminals .are shown in the drawings, namely circuit wires 23 and 2 1, respectively, cony i ten and eleven oclock morning termina 25 and 26, respectively, connecting the four [and five o clock ,morning terminals on the dials '15, 7 and .8." a

From the above description it will be seen that the arrangement is such that when the contact arms 10 and'11 are set on any of the contacts 9lof the dials 7 and 8 an electrical circuit will .be closed by the contact arm 18 when it reaches a corresponding terminal on the ,dial 15. a

For the purpose ofmoving the contact arm 18completely around the dial 15 once in twenty four h0urs,the post'17 upon which such contact arm is mounted is connected by means of a large gear 27 and a small idler gear 28 with a small driven gear 29 on the 30 of an ordinary clock, which may be disposed in a casing 31, the mechanism of he clock not being shown.

The ratio of the gears 27, 28l1and 29 is such thatQt-wo CQIIlPlBtGwl'BVOlU'GlOIlS of the framel32.

shaft 30- are revolution .o fthe shaft 17.

Thelidlerigear "2818 used for the purpose of making the larger gear 'wheel 27 travel in thesamevdirection asthelsmall gear wheel 29. Y

The 1. ear wheels 27 ,28 and- 29 may be mounte" in anysuitable frame 32 and the dial 15 maybesecure d onthe top of such If desired, a twelve "hour clock dial 34:

may be placed on ,the frame 32 so that the deviceinaybe-used as anordinary clock.

The-osci lating contact member 35 is piv- V and is normally adapted to make contact with "a terminal 38 of a conductor wire 39 that is connected With a bel the center of the the wires 12'and twelve hour to the other required to make one complete 5, as shown by the broken line position in Fig. 1, so that a circuit is ordinarily completed between the-bell 5 and the contact arm 10. f I

After the bell 5 starts to ring the occupaint of Room 1 may stop it by pressing downwardly on a button, 10 on theend of the member 35 thus breaking the contact with the terminal 38, cutting out the bell 5 and making contact with another terminal 41 that is connected through the winding of amagnet 12 ;with the conductor wire 22.

When contact is made to attract the armature 13 on the contact member 35, the contact member 35 is held in the position shown by full linesin Fig; 1, during which the current is passing through the wires 12 and 22.

Assoonas of the terminal 16 with. which it has made contact to ring the bell '5 the circuit through 22 will be broken, the magnet 42 will release the armature 13, and the action of gravity due to armature 43 will move the contact member 35 into position shownby broken lines in Fig. 1,)so that when thecontact arm 18 again completes a circuitthrough the wires 12 and22 the'bell 5 will berung. r p The operation of the oscillating switch arm and associatedmagnetand contacts th are connected with the hell 6 and with al other vbells of the system are the sameas the operation of the .similarparts I nectedwith'the bell 5; p The operation of my clock-controlledelectricsignal system Iisas follows: If the person occupyingRoom 1 wishes .tohave a call at five oclock in the morning, th tact arm 10 on the-dial 7 is placedon the five oclock morningterminal and when the contact arm 18 on the dial 15 makescontact with the five oclock morning terminal of the battery 21 through the wire 20, contact'arm 18, wire 26, contact arm 10, wire 12, contact member 35, wire 39, hell 5' and wire 22, back terminal of the battery 21, thus bell 5 in Room 1. V In a similar way the bells in any room may be rung at any desired predetermined time.

The terminal ringing the 16 and the point of the conof such. size that it'will require about one to move entirely causingt p 7 be rung for a period 0- about one minute unless they are by movement of the swi h arms 35 and 36.

' Ifmy device is used ina hotel where 'a signals are ofretu-rn call L,

provided between the rooms and the office the cut out mechanism comprising the'oscillating contact members and magnet may 1 dispensedwith and the clerk may stop the ringing of the bell by moving the contact that are con- 8 time a the contact arm 18 is moved off minute for the contact arm across the terminals, thereby i arm on the dial 7 or 8 off of the terminal on ivhich it is resting as soon as he gets a return signal from the room in which the bell is system in hotels obviates the necessity of the clerk being on duty at purpose of calling the various rooms as required.

It will be readily seen that the signal system may be connected with the ordinary bell signal system of a hotel or with the telephone system or other system that from the rooms to of a day, contact-arms pivoted to and movable over the dial, an electric cirdial, said alarm being d circuit, pivoted oscillating switch arms for each dial and alarm and located in said circuit, said switch aim being the indicating dials and said alarm. In witness whereo I hereunto subscribe my name this 26th day of March, A. D. 1918.
